ABAP_DESCRIPTION
An iterator is created for all nodes of a parsed XML document and these are used to iterate. To identify nodes that are not elements, downcasts are performed from IF_IXML_NODE to IF_IXML_ELEMENT. Both checks on regular downcasts using the predicate expression IS INSTANCE OF and downcasts using the method QUERY_INTERFACE of the interface IF_IXML_UNKNOWN are demonstrated.
